Why Choose OCH 1601?

Frequently Asked Questions (FAQ) – OCH 1601 High Silica & High Hardness RO Antiscalant

1. What is OCH 1601 RO Antiscalant?

OCH 1601 is a high-performance polymeric RO antiscalant specially formulated to prevent silica, hardness, and inorganic scale formation in Reverse Osmosis (RO) and Nanofiltration (NF) membrane systems.

2. What types of scale does OCH 1601 control?

OCH 1601 effectively controls:

• Silica Scale

• Calcium Carbonate (CaCO₃)

• Calcium Sulfate (CaSO₄)

• Barium Sulfate (BaSO₄)

• Strontium Sulfate (SrSO₄)

• Calcium Fluoride (CaF₂)

• Iron Fouling

• Manganese Deposits

• Aluminum Deposits

3. Which RO systems can use OCH 1601?

OCH 1601 is suitable for:

• Industrial RO Plants

• Packaged Drinking Water Plants

• Mineral Water Plants

• Pharmaceutical Water Systems

• Food & Beverage Industries

• Textile Industries

• Power Plants

• High TDS Borewell Water RO Systems

• Brackish Water RO Plants

• Nanofiltration (NF) Systems

4. Is OCH 1601 compatible with all RO membranes?

Yes. OCH 1601 is compatible with most polyamide thin-film composite (TFC) RO and NF membranes from leading membrane manufacturers.

5. What is the recommended dosage?

The recommended dosage is generally 2–5 ppm. For feed water with high silica, high hardness, or high TDS, the dosage may be increased based on water analysis and system operating conditions.

6. Where should OCH 1601 be dosed?

Dose OCH 1601 continuously into the feed water line after multimedia/cartridge filtration and before the RO high-pressure pump for optimum performance.

7. Does OCH 1601 improve RO recovery?

Yes. OCH 1601 helps reduce scale formation, allowing RO systems to operate at higher recovery while maintaining stable membrane performance.

8. Can OCH 1601 reduce membrane cleaning frequency?

Yes. By preventing scale and dispersing suspended particles, OCH 1601 minimizes membrane fouling and reduces the frequency of CIP (Clean-in-Place) cleaning.

9. Can OCH 1601 be used for high silica water?

Yes. OCH 1601 is specifically designed for feed water containing elevated silica levels and helps prevent silica scaling on RO membranes.

10. Can OCH 1601 be used with high hardness borewell water?

Yes. It performs effectively in borewell water containing high calcium, magnesium, and hardness, helping protect RO membranes from scaling.

11. What are the benefits of using OCH 1601?

• Controls silica and hardness scaling

• Extends RO membrane life

• Improves water recovery

• Reduces membrane fouling

• Lowers maintenance costs

• Reduces chemical cleaning frequency

• Improves plant efficiency

• Suitable for high TDS feed water

12. What packaging options are available?

OCH 1601 is available in:

• 10 kg HDPE Can

• 25 kg HDPE Can

• 35 kg HDPE Can

• 250 kg HDPE Drum

• 1000 kg IBC Tank

13. What is the shelf life of OCH 1601?

When stored in its original sealed container in a cool, dry place away from direct sunlight, OCH 1601 has a typical shelf life of 24 months.

14. Does OCH 1601 require dilution before dosing?

Yes. It is generally recommended to dilute OCH 1601 with RO permeate or clean water before dosing. The dilution ratio depends on the dosing pump capacity and plant design.

15. Why choose OCH 1601 from OCH Chemicals?

OCH 1601 is manufactured using advanced polymer technology to provide reliable scale control for challenging feed waters. It is suitable for industrial RO systems requiring high performance, higher recovery, and long membrane life while reducing operating costs.
